The only reason for why tvs scan faster is to remove flicker from the screen. 1080p 30fps is the best thing around at the moment for viewing pleasure. The only good reason to go faster is if you like playing things back in slow motion. Some cameras do that but not in 1080p. No and its insane because the eye cannot perceive anything beyond 30fps.

The reason they use fields rather than frames is to reduce analogue to air bandwidth. There are a select few camcorders that can record at a faster transport rate, such as the Panasonic HVX200 and the Sony HD1000 though I don't know if they specifically support 120 fps. Do bear in mind that a minimum 120 fps would mean a minimum shutter of at least 1/120th (probably higher to allow the image device to refresh) second otherwise you are not recording complete frames which would negate the point. Quite apart from the display frequency, the shutter speed has a bearing on motion perception regardless of the display type used. Much beyond 60 and some motion will strobe, fine for effect every now and then, but nauseating to look at all the time. On top of that by using a faster shutter you are shutting out light so you would need to use a faster aperture (softer pictures - an issue on 50" displays, much harder to focus accurately as the depth of field is reduced) Point of correction, the reason that tv systems use a specific field rate is dictated by the mains supply.
